How to set up Xiaomi Airdots headphones to work together: the complete guide

Xiaomi Airdots wireless headphones (including the Pro, Pro 2, 3 and Lite models) often encounter a problem when one of the headphones does not connect or works separately from the pair. This is due to synchronization failures between the left and right modules, improper Bluetooth settings or outdated firmware. In most cases, the problem is solved in 5-10 minutes, but it is important to act on the algorithm – chaotic manipulations can make the situation worse.

In this article, you will find step-by-step instructions for all Airdots versions, including the rare cases when headphones refuse to sync after an upgrade or physical damage. We will examine both software methods (reset, reconnect) and hardware checks (contact status, battery charge).

If you've tried to reboot your headphones or your phone, but the results haven't changed, don't rush to bring them into service. 90 percent of the time, the problem is solved at home without any special tools, and let's start with the basic steps and gradually move on to advanced methods.

1. Check the basic conditions before setting up

Before you reset or look for hidden features, make sure the minimum requirements for stable headphone performance are met:

• 🔋 Charge level: Both earbuds must be charged at least 30%. If the indicator on one of them does not burn when removed from the case, the problem may be a discharged battery or damaged contacts.
• 📱 Device Compatibility: Xiaomi Airdots Officially Supports Bluetooth 4.2+. On older smartphones (such as Redmi) 4A or Samsung Galaxy S6) There may be problems with synchronization.
• 🔄 Firmware updates: The phone must have an up-to-date OS version installed (for MIUI — at least 12.5, for Android - 9.0+). Outdated versions may not properly handle profiles A2DP.
• 🎧 Physical condition: Check if the headphones are not mechanically damaged (cracks, dents) or moisture. Even a small water intake can disrupt the Bluetooth antenna.

If at least one of the conditions is not met, further manipulations may not work, for example, Airdots Pro 2 headphones with a charge below 15% automatically turn off the secondary module to save energy, which creates the illusion of failure.

⚠️ Warning: Do not use headphones immediately after being removed from a cold room (such as from the street in winter). Condensation inside the enclosures can cause the contacts to short-circuit.

2. Standard Connection: How to Sync Headphones for the First Time

If you’ve just bought Xiaomi Airdots or reset them to factory settings, follow this algorithm for initial peg:

1. Remove both earphones from the case. Wait until both of them flash white lights (meaning they're on and ready to pair).
2. Activate Bluetooth on your phone. Go to Settings → Bluetooth and turn on device search.
3. Select Mi Airdots. The name may vary slightly depending on the model (e.g. Redmi Airdots or Mi True Wireless Earphones).

Once successfully connected, both earbuds must simultaneously play sound, and if one is silent or connected as a separate device, move on to the next section.

On Airdots Pro 2 and later, a notification may appear when you connect to the firmware update, and don’t ignore it, because outdated software often causes synchronization problems.

3. Resetting headphone settings: when and how to do

If the headphones were previously working together, but Suddenly didn't sync, the most effective method is a complete reset, which clears the memory of the headphones and returns them to the factory settings, and Importantly, after the reset, you have to reconnect them to the phone.

Instructions for all Xiaomi Airdots models (except Airdots 3, see the following paragraph for them):

1. Place both headphones in the case and close the lid.
2. Press and hold the button on the case (located behind or below) for 15-20 seconds until the indicator starts flashing red and white alternately.
3. Release the button. The headphones will automatically reset and reset.
4. Remove them from the case and repeat the connection procedure (see section 2).

For Xiaomi Airdots 3, the process is different:

1. Get both earphones out of the case.


2. Press the touch panels on both headphones simultaneously for 10 seconds.




3. Wait for the double beep and the flashing of red light.




4. Return the headphones to the case and reconnect.

⚠️ Note: Airdots Pro and Pro 2 models may need to update the firmware through the Mi Home app after reset. Without this, the headphones will connect alternately, rather than simultaneously.

4.Chronization problems: diagnosis and solutions

If the reset didn't work, the problem may be one of the following: Go through the checklist to find the root of the malfunction:

Special attention is paid to firmware. Headphones Xiaomi Airdots Pro 2 with software version below 1.4.0.7 have a bug that causes the right earphone to turn off after 5 minutes of use.

1. Install Mi Home from Google Play or App Store.
2. Put the headphones on the phone.
3. Open the application, go to Profile → Settings → Firmware update.
4. If a new version is available, follow the instructions on the screen.

💡

If the Mi Home app doesn’t see headphones, try connecting via Mi AI (for Chinese firmware versions) or use alternative software like Airdots Flasher (requires root rights on your phone).

5. Advanced methods: manual synchronization and firmware

If standard methods don't work, you'll have to use manual synchronization methods, which take longer, but they're effective in 95 percent of the "severe" cases.

Method 1: Forced binding through the case

This method works for Airdots Basic and Pro:

1. Put both headphones in the case and close the lid.
2. Open the lid, only take out the right earpiece.
3. Wait until it flashes white, then return it to the case.
4. Repeat steps 2-3 for the left earpiece.
5. Close the lid for 10 seconds, then remove both headphones - they should sync.

Method 2: Firmware via PC (for power users)

If the headphones are not updated through the Mi Home, you can manually flash them using the Airdots Flasher:

1. Download the utility from GitHub.
2. Connect the headphones to the PC via Bluetooth.
3. Run AirdotsFlasher.exe and select your headphone model.
4. Press Flash and wait for the process to complete (don’t turn off the headphones!).

⚠️ Warning: Continuous interruption of firmware can permanently disable your headphones. Use only original firmware files from trusted sources (e.g. forums). 4PDA).

💡

Hand-held firmware is the last resort, and most of the time, it helps to upgrade through Mi Home or reset your settings, and only use it if other methods have failed.

6. Frequent User Errors and How to Avoid Them

Many of the problems with Xiaomi Airdots are caused by unobvious user actions, and here are the most common mistakes and how to prevent them:

• 🔌 Using a non-original cable to charge the case, cheap cables may not provide enough current, which causes the headphones to charge unevenly. Always use a kit cable or a certified one. USB-C.
• 📴 Turn off Bluetooth on your phone while you're syncing. If you interrupt the connection, the headphones can "forget" each other.
• 🔊 Change the audio settings manually. MIUI When manually adjusting the equalizer, the profile may be lost A2DP, This causes the connection between the headphones to break.
• 🌡️ Operating at extreme temperatures. Headphones are designed to work at 0-35°C. Use in the cold or in direct sunlight reduces battery life and may cause failures.

Another common problem is connecting your headphones to multiple devices at once, for example, if you connect them to your phone and laptop, they may get confused about priorities. To avoid this, always delete old devices from your headphones' memory before you pair them again:

On Android: Settings → Bluetooth → ⚙️ next to Mi Airdots → Delete device


On iOS: Settings → Bluetooth → i next to Mi Airdots → Forget this device

7. Hardware problems: when you need help from the service

If all the software methods have been tried, but the headphones still don't work together, the problem may be the hardware, and here are some signs you should contact the service center:

• 🔋 One of the headphones is not charged (the indicator does not burn when placed in the case).
• 🎛️ Extraneous sounds (wheezing, crackling) even after resetting settings.
• 📶 Permanent communication breaks less than 1 meter from the phone.
• 💧 Corrosion traces on case contacts or headphones.
